"Construction and comparison of Louisiana's conventional and alternative base courses under accelerated loading" (1998) Metcalf, J. The Transportation Asset Management Case Study series is theresult of a partnership between State departments of trans-portation (DOTs) and the Federal Highway Administration(FHWA) Office of Asset Management. Construction and comparison of Louisiana's conventional and alternative base courses under accelerated loading. Institute of Recyclable Materials United States.

Experimental sections on the 2.8 kilometer (1.7 miles) Test Track are cooperatively funded by external sponsors, most commonly state DOT's, with subsequent operation and research managed by NCAT. The Alabama DOT funded the construction of the track at NCAT with anticipation that operation of the track would be a cooperative effort between several sponsors.

The facility is expected to clarify the relationship between methods and performance such that design and construction policy in the future can be objectively guided by life cycle costs.

The Test Track (referred to occasionally as the Track) is the result of industry and government committing to work together to improve the quality of flexible pavements. If you use the 2017 version of the CCF a Memorandum for the Record (MFR) is not required through August 31, 2023. Unlike conventional efforts on public roadways, research at the NCAT Test Track is conducted on a closed-loop facility where axle loadings are monitored and environmental effects are similar for every mix. Yes, DOT-regulated employers and their service agents (collectors, laboratories, Medical Review Officers (MRO)) are authorized to use the 2017 version of the CCF only for urine collections until August 31, 2023. The renewal fee for the RBEC and the RRO is 500 for members and 600 for nonmembers. In this case, the renewal fee is a total of 400 for members, 500 for nonmembers. This allows validation of laboratory tests and pavement design procedures under traffic similar to that which is observed on roadways. The RBEC can be listed as a single designation, eliminating reference to the RRC, RWC and REWC designations. The primary objective of the test track was to provide an accelerated loading facility that could be used to rapidly test a large number of test sections simultaneously. The Alabama DOT in conjunction with National Center for Asphalt Technology (NCAT) decided that a test track was the best approach to provide practical answers to existing performance issues. As the traffic has increased, better laboratory tests and material specifications have been developed to help ensure that high quality mixtures are produced. As the amount of traffic has increased (higher volumes, higher loads, and increased tire pressures) the ability of these laboratory tests to evaluate potential performance has become more important. Below is a state-by -state listing of links to all state department of transportation, Disadvantaged Business Enterprise (DBE) program and DBE directory web sites.Empirical laboratory tests have been used for years to test hot mix asphalt (HMA) to determine the potential for various mixtures to perform well. ![]()
